good morning, everyone. i'm poppy harlow. welcome to our continuing coverage of the boston coverage. news that federal investigators will be back at work today here in boston looking for more clues in the bombing. the fbi at this point is not saying what, if anything, they found. but we do know what they were looking for, that is tsarnaev's laptop. that could have important information on the planning of the boston attacks. new information coming in from

the russia. bill, hello to you. first of all, what are we learning about the mother at this hour? >> poppy, good morning. cnn is being told that russian authorities intercepted a communication between the bombing suspect's mother and one of the bomb suspects. we were told this, not by russian authorities, but a u.s. official who said the intercept was made back in 2011, but made available to u.s. authorities only in the last few days. now, we know that back in two 2011 the russians asked the fbi to investigate tamerlan tsarnaev. the fbi looked into him and found no evidence that he was a threat and they went back to the russians with more questions, but never heard anything after that. now, it is difficult to determine the significance of this communication, this intercepted communication, but it raises a key question. that is, had the fbi known of its existence sooner, would that

investigation have been conducted differently? would this ultimate conclusions have been different, as well. poppy? >> that is absolutely the key question. we also don't know whether or not russia intercepted those polls before or after they warned the united states about tamerlan tsarnaev. russian president vladimir putin has been stressing all week that the united states and russia can work closer together to prevent tragedies like this but mike rogers says he thinks "russians have more ninformation than they're sharing." how open is the russian government being at this point? >> well, in terms of public o n openness, there is almost none, whatever. this is the russian security service, their internal police, if you like. what did they know about

tamerlan tsarnaev. why they were worried enough to look into him. we haven't looked back on this and that isn't a surprise because this is a highly secretive organization. the soviet police, the kbg. from the government we haven't heard a lot either. vladimir putin offers greater information and in reference to what russia a knew at the time back in 2011 it is only fair with great regret that they haven't provided information of operational significance. still important questions about the operation that went on around that 2011 period, but, since the bombings, both american and russian officials are saying they are working very closely together. >> that is the initial message. phil black, thank you for joining us from mascow. thank you. we know that tamerlan tsarnaev and his mother was on a

clearing house list for all international terrorist identities. basically, it's a watch list. about half a million names in da database. now, the percent of the people on the list are u.s. citizens or legal permanent residents. congress established this list back in 2004. and less than 5% are u.s. citizens or legal, permanent residents. the administration is talking about its decision to read dzhokhar tsarnaev his miranda rights. pamela brown is live for us this morning in devon, massachusetts. she is standing outside the prison hospital where tsarnaev is being held. what can you tell us? >> poppy, good morning to you. a lot of focus whether rights

were issued too soon. they asked attorney general eric holder for a comment and for the first time he responded to this issue. here's what he had to say. >> are you familiar with this report that russian authorities wi wiretapped one of the bombing suspects and that he was speaking with about his mother in jihad in 2011. can you talk about that? can you comment aon the suspect being mirandize and whether that was appropriate? >> that was consistent with the law. everything he's done appropriately and we got good leads. >> he taukdlked about the two d under law by the public law. then the miranda rights can be

administered. that's what happened in this case. however, we're hearing from chairman of the intelligence committee, mike rogers, and he believed the miranda a oitrighte issued too soon and they might have been able to gain more valuable information from the suspect, if they had more time with him. but, also, you have to remember he has an attorney now who may be advising him not to speak. >> we're also learning, more, pamela, about the arrest of two of tsarnaev's friends. what do we know on that front? >> there's been a lot of talk about these two students from umass dartmouth that were arrested shortly after everything went down last friday. essentially these two students were friend with dzhokhar tsarnaev. no way were they at the plot.

the department of homeland security said they're being held on administrative visas. authorities are holding them on that and also using this as an opportunity to gain valuable information about dzhokhar tsarnaev. trying to gain a clearer picture of who he is and why he allegedly carried out the attacks. >> buying time is a way you can look at it. pamela, the search of the la landfill, that is over, that is concluded. did authorities find anything significant? >> well, poppy, i have been communicating with the fbi and essentially now that the search has ended they're telling us that they're not publicly speak about whether anything was found aat that landfill. they were searching for what they believed was a laptop belonging to the suspect. they were led there from the landfill himself and from other

questioned in this investigation. but at this point authorities are not saying whether they found anything, but you have to think, poppy, that they really wanted to find this, they believe they could have found some critical evidence to help in this investigation and they probably won't give up until they find something. >> i was just going to say, they're probably not going to wrap up after that amount of time. pamela brown, thank you very much. tonight on cnn following the trail of terror from boston to the suburbs of the war-torn. who were the two bombers and, critically, what influenced them. boston terror, behind the boston balm abinges at 10:00 eastern tonight. back to our special coverage of boston in a moment, but just days after an elvis impersonator was cleared, a new suspect charged with sending poison letters to president obama and other officials. we're going to tell you who he

is and what other crimes he is accused of. plus, thousands of runners are taking part in this morning's madrid marathon. why security is even tighter and this is not just because of boston. i have low testosterone. there, i said it.

how did i know? well, i didn't really. see, i figured low testosterone would decrease my sex drive... but when i started losing energy and became moody... that's when i had an honest conversation with my doctor. we discussed all the symptoms... then he gave me some blood tests. showed it was low t. that's it. it was a number -- not just me.

and martin richard. a new case has been made in the ricin letters. this comes just days after prosecutors dropped charges against another man. alina is following the story from tupelo, mississippi. alina? >> the judge of a son who received one of those ricin letters say he hopes it is a step towards justice for his family. this is who authorities now believe mailed the three ricin laced letters. federal prosecutors have charged james everett dusky. he is known of possessing a biological agent for use as a weapon. that agent according to the u.s. attorney's office, was ricin.

>> this could have been devastating. mom could have died. >> reporter: steve holland's mother is the mississippi judge who received one of the letters. dutschke ran against him in 2007. >> he was a mad personality. vicious kind of guy. he attacked me personally and even my entire family. >> reporter: last week charge as were dropped against the first suspect in the case, an elvis impersonator. curtis said he had been framed and pointed to dutschke as a possible suspect. they searched the marshal arts studio dutschke used to run and his home in tupelo. >> i met with the fbi and i consulted to a search and signed a piece of paper saying, go ahead, search the house. i don't have anything at all to do with this. >> reporter: an attorney representing the 41-year-old on

a separate case said the marshal arts studio closed after charged with child molestation earlier this year. he is expected to be in federal court tomorrow morning. we are hoping to learn more about the arrests and, also, about what it was that led authorities to him. poppy? >> alina for us in tupelo, mississippi, alina, thank you. thousands of people are are hitting the pavement for another marathon this morning and, as you can imagine, security is tight for the race which is being held in madrid. we'll take you there live, next.

just another sign of the strength in this wonderful city, boston strong written on sneaker upon sneaker here on boylston. it has been an honor to report here, meet the people. a line that stretched for quite

a ways for people to get in and pay their respects to boston. boston strong. well, the spirit of marathon runners still undaunted after the boston terror attacks. after a moment of silence for boston victims, more than 30,000 runners participated in this weekend's country music marathon in nashville. it is the biggest race in the united states since the boston attack. runners we spoke to said they felt safe. hundreds of law enforcement officers and security personnel were, of course, on hand. about 26,000 people in spain are running in today's marathon in madrid. spanish authority increased security following the attack here in boston and last week they actually arrested two terror suspects. both of those men accused of having connections to an al qaeda group and islamic extremists. the two men have a profile similar to the two boston bombing suspects. al goodman live from madrid this

morning. hello, al, tell me first about the atmosphere there at the marathon. >> hi, poppy. well, thankfully this is just a thrilling, competitive marathon, as you can see behind me, we're near the finish line. but clearly the boston marathon balm abing seemingly on everyone's minds and all 26,000 runners paused for a moment of silence before they started the race this day in honor of the bostonm haves and also many of them had on black arm bands, said it was very much on their minds. >> since those arrests were made last week, how has security been increased there at the marathon and talking to runners, were any of them worried? did runners not feel safe? >> we talked to a lot of runners in recent days and didn't find anyone who said that they felt

the slightest concern. now, security has had a lot of security experience dating back to the madrid train bombings in 2004. security for this event was beefed up with hundreds more national police officers backing up the local police officers and the private security guards. one official telling us, they just didn't want to make the race safe, they wanted to convey the message to everyone. spectators and runners that it is safe. so far, that's what we have. poppy? >> al goodman live for us in madrid. al, thank you. president obama took a break from it all last night and became comedian in chief at the annual white house correspondence dinner. >> this whole controversy about jay-z going to cuba. it's unbelievable. i got 99 problems and now jay-z's one. >> who knew jay-z would make it into the president's speech. a big night across the board.

the entire speech from president obama for you, next. rone, my doctor and i went with axiron, the only underarm low t treatment. axiron can restore t levels to normal in about 2 weeks in most men. axiron is not for use in women or anyone younger than 18 or men with prostate or breast cancer. women, especially those who are or who may become pregnant and children should avoid contact where axiron is applied as unexpected signs of puberty in children or changes in body hair or increased acne in women may occur. report these symptoms to your doctor. tell your doctor about all medical conditions and medications. serious side effects could include increased risk of prostate cancer; worsening prostate symptoms; decreased sperm count; ankle, feet or body swelling; enlarged or painful breasts; problems breathing while sleeping; and blood clots in the legs. common side effects include skin redness or irritation where applied, increased red blood cell count, headache, diarrhea, vomiting, and increase in psa. ask your doctor about the only underarm low t treatment,

axiron.

welcome back. mortgage rates fell to another record low this week. take a look.

a phrase that has really defined this city in the past few weeks. boston strong. you see it there on a painting of the american flag and the american flag itself. many of them sprinkled around this makeshift memorial right in coply square on boylston street. as the day progressed yesterday, we saw a long line of people just to get in here and pay their respects writing messages on boards that are then taken to city hall. messages of hope, messages of strength and messages of support for this wonderful city. welcome back, and thank you for starting your sunday morning with us. i'm poppy harlow. a rough few weeks for president obama and, frankly, for the entire country. the president visit memorials for people here in boston and in west, texas, after that explosion. last night an opportunity to

lighten the mood. that's right, all at the annual white house correspondence dinner. the yearly red carpet event for washington's elite celebrities and some of us, the press. the president walked on stage to a rap song "all i do is win." >> i'd like to introduce the president of the united states. >> thank you. thank you, everybody. how do you like my new entrance music? rush limbaugh warned you about

this, second term, baby. we're changing things around here a little bit. actually, my advisors were a little worried about the new rap entrance music. they are a little more traditional. they suggested that i should start with some jokes at my own expense. just take myself down a peg. i was like, guys, after 4 1/2 years, how many pegs are there left? i want to thank the white house correspondents, ed, you're doing an outstanding job. we are grateful for the great work you've done. if all the dignitaries were

here, i'd especially want to say thank you to ray oderino who does outstanding work for our country and all the men and women in uniform every single day and, of course, our extraordinary first lady, michelle obama. everybody loves michelle. she's on the cover of "vogue," high poll numbers. but don't worry, i recently got my own magazine cover. look, i get it. these days i look in the mirror and i have to admit, i'm not the strapping young socialist that i used to be.

get a little gray. and, yet, even after all this time, i still make rookie mistakes. like, i'm out in california we're at a fund-raiser having a nice time and i happened to mention that pamela harris is the best-looking attorney general in the country. as you can imagine, i got in trouble when i got back home. who knew eric holder was so sensitive? and then there's the easter egg roll, which is supposed to be just a nice, fun event with the kids. i go out on the basketball court, took 22 shots. made two of them. that's right. two hits, 20 misses.

the executives at nbc asked, what's your secret? so, yes, maybe i have lost a step. but some things are beyond my control. for example, this whole controversy about jay-z going to cuba. it's unbelievable. i have 99 problems and now jay-z's one. that's another rap reference. of course, everybody has plenty of advice. maureen dodd said i could solve

all my problems if i was just more like michael douglas in "the american president." i know michael's here tonight. michael, what's your secret, man? could it be that you were an actor in a liberal fantasy? my bet has something to do with it. i don't know. check in with me. maybe it's something else. anyway, i recognize that this job can take a toll on you. i understand second term you need a burst of new energy. try some new things and then my team and i talked about it, we're willing to try anything. we borrowed one of michelle's tricks.

i thought this looked pretty good. but, no bounce. anyway. i want to give a shout out to our headliner conan o'brien. i was just talking to ed and i understand that when the correspondents' association was considering for this gig, they were face would the age-old dilemma. off aer it to him now or wait for five years and then give it to jimmy fallon? that was a little harsh. i love conan.

and, of course, the white house press corps is here. i know cnn has taken some knocks lately, but the fact is i admire their commitment to cover all sides of the story, just in case one of them happens to be accurate. some of my former advisors have switched over to the dark side. for example, david axelrod now works for msnbc. which is a nice change of pace since msnbc used to work for david axelrod. the history channel is not here. i guess they were embarrassed about is the whole obama is a devil thing.

of course, that never kept fox news from showing up. they thought the comparison was not fair to satan. but the problem is that the media landscape is changing so rapidly. you can't keep up with it. i remember when buzz feed was just something i did in college around 2:00 a.m. it's true. recently, though, i found a new favorite source for political news. these guys are great. i think everybody here should check it out. they tell it like it is.

it's called whitehouse.gov. i cannot get enough of it. the fact is, i really do respect the press. i recognize that the press and i have different jobs to do. my job is to be president. your job is to keep me humble. frankly, i think i'm doing my job better. but part of the problem is everybody is so cynical. we're constantly feeding cynicism, conspiracies. you remember a few months ago my administration put out a photograph of me going skeet shooting at camp david. do you remember that? and quite a number of people insisted that this had been photoshopped. but tonight i have something to confess. you were right.

guys, can we show them the actual photo? we were just trying to tone it down a little bit. that was an awesome day. there are other new players in the media landscape, as well. like superpacs. did you know that sheldon adelson spent $1 million on ads. you have to really dislike me to spend that kind of money. that is oprah money. you could buy an island and call it nobama for that kind of money. sheldon would have been better off offering me $100 million to

drop out of the race. i probably wouldn't have taken it. but i thought about it. michelle would have taken it. you think i'm joking. i know republicans are still sorting out what happened in 2012. but one thing they all agree on is they need to do a better job reaching out to minorities. and, look, call me self-centered, but i can think of one minority they could start with. hello.

think of me as a trial run, you know. see how it goes. if they won't come to me, i will come to them. recently i had dinner, it's been well publicized. i had dinner with a number of the republican senators. i'll admit it wasn't easy. i proposed a toast, it died in committee. of course, even after i've done all this, some folks still don't think i spend enough time with congress. get a drink with mitch mcconnell, they ask. really? why don't you get a drink with mitch mcconnell. >> the president did not stop there, much more of his speech to come, including who would

play president obama in a movie about his life. you're watching "cnn sunday morning" live from boston. thanks for waking up with us. man: how did i get here? dumb luck? or good decisions? ones i've made. ones we've all made. about marriage. children. money. about tomorrow. here's to good decisions. who matters most to you says the most about you. at massmutual we're owned by our policyowners, and they matter most to us. ready to plan for your family's future? we'll help you get there. ♪ [ male announcer ] every car we build

cnn sunday morning. i want to take you back to the white house correspondents' dinner where president barack obama is talking about his offensive in washington. >> i am not giving up. in fact, i'm taking my charm offense on the road. a texas barbecue with ted cruz. kentucky blue grass concert with rand paul. and a book burning with michele bachmann. my charm offense has helped me learn a few things in congress. it turns out, absolutely nothing. but the point of my charm offensive is simple. we need to make progress on

simple issues. take the sequester. republicans fell in love with this thing and now they can't stop talking about how much they hate it. it's like we're trapped in a taylor swift album. one senator who has reached across the aisle recently is marco rubio. but i don't know about 2016. i mean, the dguy has not even finished a single term in the senate and he thinks he's ready to be president. kids these days. i, on the other hand, have run my last campaign. on thursday, as ed mentioned, i went to the opening of the bush presidential library in dallas. it was a wonderful event and that inspired me to get started on my own legacy, which will

actually begin by building another edifice right next to the bush library. can we show that, please. i'm also hard at work on plans for the obama library. some have suggested that we put it in my birthplace, but i'd rather keep it in the united states. did anybody not see that joke coming? show of hands. only gallup. now, speaking of presidents and

their legacies. i want to acknowledge a wonderful friend, steven spielberg and daniel day lewis, who are here tonight. we had a screening of their most recent film "lincoln," which was an extraordinary film. i am a little nervous about steven's next project. i saw a behind the scenes look on hbo. well, let's just check it out. roll the tape. >> well, i was thrilled that lincoln was a success and i was thinking about what to do next. in the middle of the night i woke up and it hit me. obama. why wait? picking the right actor to play obama a, that was the challenge. who is obama really? we don't know. we never got his transcripts and they say, i needed someone who could dive in and really become barack obama. as it turns out, the answer was right in front of me all along.

daniel day-lewis. he becomes his characters. hawkeye from "last of the moh-- nailed it. >> hello, ohio. i love you back. look, look, let me be clear about this. the cosmetics were challenging. >> but once we had daniel to play obama, we had to cast the rest of the team. >> working with a legend like daniel is intimidating, but he makes everybody better. without him, i could have never played joe biden. i am joe biden. >> the hardest part, trying to understand his motivations. why did he pursue health care

first? what makes him tick? why didn't he get mad? if i was him, i would be mad all the time. but i'm not. i'm daniel day-lewis. >> remarkable transformation. do i really sound like that? well, groucho marks once said and that's not carl, the other guy. he once told an audience, before

i speak, i have something to say. along those same lines, i want to close on a more serious note. obviously, no shortage of news to cover over these past few weeks and these have been some very hard days for too many of our citizens. even as we gather here tonight, our thoughts are not far from the people of boston and the people of west, texas. there are families in the midwest who are coping with some terrible floods. so, we've had some difficult days. but even when the day seemed darkest, we have seen humanity shine at a its brightest. we've seen first responders and national guardsmen who dashed into danger. law enforcement officers who lived their oath to serve and to protect. and everyday americans who are opening their homes and their hearts to perfect strangers. and we also saw journalists at

their best. especially those who took the time to wade upstream to the torrent of digital rumors and chase down facts and pain ste painstakingly to put the pieces together and tell stories that demanded to be told. if anyone wonders, for example, if newspapers are a thing of the past, all you needed to do was picked up or logon to papers like "the boston globe." when their communities and the wider world needed them most, they were there. making sense of events that might at first brush seemed beyond our comprehension. that's what great journalism is and that's what great journalists do. and that's why, for example, pete williams new nickname around the newsroom is big papi.

and in these past few weeks, as i've gotten a chance to meet many of the first responders and the police officers and volunteers who raced to help when hardship hits, i was reminded, when i always meet our men and women in uniform whether they're in war theater or back home or at walter reed, bethesda, i'm reminded all these folks don't do it to be honored. they don't do it to be celebrated. they do it because they love their families and they love their neighborhoods and they love their country. and, so, these men and women should inspire all of us in this room. to live up to those same standards. to be worthy of their trust. to do our jobs with the same

fidelity and same integrity and the same sense of purpose. and the same love of country. because if we're only focused on profits or ratings or polls, then we're contributing to the cynicism that so many people feel right now. and, so those of us in this room tonight, we're incredibly lucky. the fact is, we can do better. all of us. those of us in public office, those of us in the press, those who produce entertainment for our kids, those with power, those with influence. all of us, including myself, we can strive to value those things that i suspect let most of us do the work that we do in the first

place. because we believed in something that was true. and we believed in service and the idea that we can have a lasting, positive impact on the lives of the people around us. and that's our obligation. that's a task we should gladly embrace on behalf of all those folks who are counting on us. on behalf of this country that has given us so much. thank you, all, to the white house correspondents for the great work that you do. god bless you all. my god bless the united states of america. >> we will have much more coming up on "cnn early start weekend," including surprising and troubling information about the boston bombing suspect's mother. i'm poppy harlow live from boston this morning. stay with us. copd makes it hard to breathe...
